My H&S 6.7 vs H&S 6.4 experience

[JsnMR2]

So I have seen this 6.4 running around town here and there. Looks like maybe a 6-8" lift, dual stacks, 22" wheels and maybe 37's, ect.. Today I finally was able to get next to him.

At a light he asked which programmer so I told him H&S, and then he said he was also on an H&S. I asked what tune he was on and he said 300. He also had dpf delete/stacks, intake, intercooler, head studs, but no egr block off.

We both did a 4WD launch and I was fully expecting to get my *** handed to me.. Something happened on the first run and I got the hit and pulled away big time so we let off. We stopped again, and did another 4WD launch. We got an even start but again something happened and I pulled away and we let off. After that, we did a couple rolling starts. Each time I pulled about 1 truck length, and he started to slowly catch up, but had to shut down around 80. (we went on three honks each time) So basically on the initial hit, I pulled, and after getting up to speed, he'd slowly catch up but never passed me.

Needless to say I was pleasantly surprised with the outcome. I thought he was going to pull on me like crazy. Seems like the 6.7 has a lot of low end to it compared to the 6.4 (at least that one). If we kept going, he would have passed me eventually.

I don't do a lot of racing in this truck, but I had been waiting to get a piece of a 6.4 lol.

Just excited, so I figured I'd share

My truck is H&S minimax, intake, dpf delete, egr block off. 3" lift and 35's. The truck has been solid. Perfect shifts from the transmission, no weird hiccups and other issues. Thanks H&S!

Nice! I love my 6.7 3.55 too, can't wait to get deletes and tuned.

Just a heads up though, the 6.4 guys will turn this thread into a pissing match for sure.

big tires hurt performace really bad i used to have a 6.4 with 35s it felt like i lost 50hp with the bigger tires. got a 6.7 dually now with the same h&s love it so far. 6.7 does have alot more low end torque. 6.4 is a faster engine tho

lol.. this makes me want a 6.7 more and more.. i have the itch for a new truck for some reason.. but i cant justify getting rid of mine.. its running perfect right now... (knock on wood)

[08powerstroke6.4]

main reason i got rid of my 6.4 was i wanted a 1 ton and for a low mile 6.4 ur lookin at 38k with really low miles and i got a brand new 6.7 for 45k and its a lariet as well just seems dumb to buy used.

I hear ya, but I can't justify to the old lady starting my payments again when I'm over half way getting this one paid off, even if its a newer truck with similar payments
